Recent Accounting Standard Pronouncements

Below are recent accounting standard updates that we are still assessing to determine the effect on our Condensed Consolidated Financial Statements. We do not believe that any other recently issued accounting standards could have a material effect on our Condensed Consolidated Financial Statements. As new accounting pronouncements are issued, we will adopt those that are applicable under the circumstances.



Recently Issued Accounting Standards Adopted
Standard	Description	Date of adoption	Effect on the Financial Statements or Other Significant Matters
Clarifying the Definition of a Business	This update clarifies the definition of a business and addresses whether transactions should be accounted for as asset acquisitions or business combinations (or divestitures). The guidance includes an initial threshold that an acquired set of assets will not be considered a business if substantially all of the fair value of the assets acquired is concentrated in a single tangible or identifiable intangible asset (or group of similar assets). If the acquired set does not pass the initial threshold, then the guidance requires that, to be a business, the set must include an input and a substantive process that together significantly contribute to the ability to create outputs. Different factors are considered to determine whether the set includes a substantive process, such as the inclusion of an organized workforce. Further, the guidance removes language stating that a business need not include all of the inputs and processes that the seller used in operating the business.	January 1, 2017	We early adopted this new standard and will apply it prospectively when determining whether transactions should be accounted for as asset acquisitions (divestitures) or business combinations (divestitures). During the nine months ended September 30, 2017, we applied the new guidance when determining whether certain product divestitures represented sales of assets or businesses.
Improvements to Employee Share-Based Payment Accounting	This guidance is intended to simplify several aspects of the accounting for share-based payment award transactions. It will require all income tax effects of awards to be recorded through the income statement when the awards vest or settle as opposed to certain amounts being recorded in additional paid-in capital. An entity will also have to elect whether to account for forfeitures as they occur or by estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change (as currently required). The guidance will also increase the amount an employer can withhold to cover income taxes on awards.	January 1, 2017	We adopted this standard as of January 1, 2017. We elected to estimate the number of awards expected to be forfeited and adjust the estimate when it is likely to change, consistent with past practice. We did not change the amounts that we withhold to cover income taxes on awards. As the requirement to record all income tax effects of vested or settled awards through the income statement is prospective in nature, there was no cumulative effect of adopting the standard on our balance sheet.

Revenue from Contracts with Customers	The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: identify the contract(s) with a customer; identify the performance obligations in the contract; determine the transaction price; allocate the transaction price to the performance obligations in the contract; and recognize revenue when (or as) the entity satisfies a performance obligation. This guidance allows for two adoption methods, full retrospective approach or modified retrospective approach.	January 1, 2018	We continue to evaluate the implications of adoption of the new revenue standard on our Consolidated Financial Statements. We have completed an initial assessment and are in the process of quantifying the adoption impact, if any, related to certain topics identified through our evaluation process. Our assessment of the new revenue standard has been focused on, but has not been limited to, the concepts of over-time versus point-in-time revenue recognition patterns, variable consideration, and identification of performance obligations. We will not complete our final assessment and quantification of the impact of the new revenue standard on our Consolidated Financial Statements until the adoption date. Our analysis indicates that certain contract manufacturing and private label arrangements may require revenue recognition over-time in situations in which we produce products that have no alternative use and we have an enforceable right to payment for performance completed to date, inclusive of a reasonable profit margin. This may result in an acceleration of revenue recognition for certain contractual arrangements as compared to recognition under current accounting literature. We plan to adopt the new revenue standard effective January 1, 2018 using the modified retrospective method.
Intra-Entity Asset Transfers of Assets Other Than Inventory	Under the new guidance, the tax impact to the seller on the profit from the transfers and the buyer’s deferred tax benefit on the increased tax basis would be recognized when the transfers occur, resulting in the recognition of expense sooner than under historical guidance. The guidance excludes intra-entity transfers of inventory. For intra-entity transfers of inventory, the Financial Accounting Standards Board ("FASB") decided to retain current GAAP, which requires an entity to recognize the income tax consequences when the inventory has been sold to an outside party.	January 1, 2018	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
Financial Instruments - Recognition and Measurement of Financial Assets and Liabilities	The objective of this simplification update is to improve the decision usefulness of financial instrument reporting, and it principally affects accounting for equity investments currently classified as available for sale and financial liabilities where the fair value option has been elected. Entities will have to measure many equity investments at fair value and recognize changes in fair value in net income rather than other comprehensive income as required under current U.S. GAAP.	January 1, 2018	We have identified certain investments that will require an adjustment, however, at this time, we are unable to estimate the impact of adopting this standard as the significance of the impact will depend upon our equity investments as of the date of adoption.



Recently Issued Accounting Standards Not Yet Adopted (continued)
Standard	Description	Effective Date	Effect on the Financial Statements or Other Significant Matters
Leases	This guidance was issued to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. For leases with a term of 12 months or less, lessees are permitted to make an election to not recognize right-of-use assets and lease liabilities. Upon adoption, lessees will apply the new standard as of the beginning of the earliest comparative period presented in the financial statements, however lessees will be able to exclude leases that expire as of the implementation date. Early adoption is permitted.	January 1, 2019	We are currently evaluating the implications of adoption on our Consolidated Financial Statements and have commenced the first step of identifying a task force to take the lead in implementing the new Lease standard.
Derivatives and Hedging	This update was issued to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. In addition, the amendments simplify the application of hedge accounting in certain situations. Under the new rule, the entity’s ability to hedge non-financial and financial risk components is expanded. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and also eases certain documentation and assessment requirements. Early adoption is permitted.	January 1, 2019	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
Measurement of Credit Losses on Financial Instruments	This guidance changes the impairment model for most financial assets and certain other instruments, replacing the current "incurred loss" approach with an "expected loss" credit impairment model, which will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, and off-balance sheet credit exposures such as letters of credit. Early adoption is permitted.	January 1, 2020	We are currently evaluating the new standard for potential impacts on our receivables, debt, and other financial instruments.
Intangibles - Goodwill and Other Simplifying the Test for Goodwill	The objective of this update is to reduce the cost and complexity of subsequent goodwill accounting by simplifying the impairment test by removing the Step 2 requirement to perform a hypothetical purchase price allocation when the carrying value of a reporting unit exceeds its fair value. If a reporting unit’s carrying value exceeds its fair value, an entity would record an impairment charge based on that difference, limited to the amount of goodwill attributed to that reporting unit. The proposal would not change the guidance on completing Step 1 of the goodwill impairment test. The proposed guidance would be applied prospectively. Early adoption is permitted.	January 1, 2020	We are currently evaluating the implications of adoption on our Consolidated Financial Statements.
